在Orgin NX上部署Deepseek

这几天在思考部署Deepseek，手边没有合适的硬件，就想着用NX部署一个，主要流程记录如下。

  1. 手动下载ollama
    地址：https://github.com/ollama/ollama/releases
    系统是ubuntu22.04，需要下载两个文件：
  • ollama-linux-arm64.tgz
  • ollama-linux-arm64-jetpack6.tgz

先下载好，上传到NX板子系统内，备用。直接命令行下载会很慢，而且容易出错。

  1. 使用修改后的脚本，和以上两个文件放在一起，运行脚本。
    脚本主要修改了下载部分:
  • 改为使用本地包安装。
  • 更改为局域网可访问。

  2. 使用bash install_ollama.sh运行脚本，如无异常，将会在几分钟内完成安装，并输出如下信息：

  1. 然后在NX里新建命令行窗口，运行如下命令，验证安装成功。
ollama -v

返回

ollama version is 0.5.11
  1. 拉取Deepseek 1.5B模型。
    这里考虑到NX的显存和算力，只用了1.5B的模型。
ollama run deepseek-r1:1.5b

拉取模型完成后，显示如下：
